Specification of Letters Patent.

Application filed June 12, 1914'. Serial No. 844,650,

T all whom it may concern:

Be it known that 1, ROBERT J. CLEELAND, a citizen of the United States of America, residing in the city of Springfield, county of Hampden, and State of Massachusetts, have invented new and useful Improvements in Apparatus for Use in Candy-Making, of which the following is the specification.

This invention relates to an apparatus for crystallizing candy and is especially adapted for saving labor in handling large quantities of candy in a short space of time.

On many grades of candy, the crystallizing process is briefly as follows: The candy prior to the process is formed of the required size and shape. It is then put in suitable pans, the quantity in each pan being about the amount the pan can carry. Syrup which has been boiled to the required degree at a given temperature is put in each pan until the candy therein is immersed. The pans, full of syrup and candy, are left undisturbed for a given length of time during which time the candy absorbs or takes on a necessary coating of the syrup crystallizing on the candy. The excess syrup is then drained from the pans, and the candy is left with a crystallized surface coating. The usual steps are then in brief-t0 fill the pans with candy, then with syrup, allow them to stand a given time, drain off the syrup, and take out the candy. In this process, it has been customary to use pans of rather small capacity in order to permit an operator to handle them conveniently. On account of the weight of the pan full of candy and sometimes very hot syrup, it would be dangerous as well as inconvenient for the pan, under ordinary practice, to be of any considerable size.

The object of this invention is to provide novel and useful rack and pans for use in the crystallizing process whereby the goods crystallized may be handled more conveniently than heretofore, and, therefore, in larger quantities at a greater rate of speed.

A further object is to provide an improved rack for crystallizing pans adapted to hold the latter so that any one may be separately removed at will to be filled with candy, scraped, or otherwise used and, when on the rack, may be with others held either in posi tion to permit the crystallizing process to continue or tipped into draining position to separate the excess syrup from the candy.

A further object is to provide an improved rack for use in crystallizing candy embodying supporting means for separate tiers of crystallizing pans from which any of the pans may be separately removed at willand means to tip the pans in independent groups to drain oif the syrup.

A further object is to provide an improved rack having improved draining means for the excess syrup in the crystallizing process.

A further object is to provide improved rack and pans of general application in the crystallizing process whereby large quantities of candy may be handled expeditiously with a resulting saving in floor space, labor, and time.

Other objects of the invention will appear as the description thereof proceeds and will be defined more particularly in the annexed claims.

My invention, in the preferred form chosen for the purpose of illustration, comprises, in general, a portable rack adapted to support at different levels separate groups of crystallizing pans, with means for tipping at will each group into syrup-draining position andholding it in that position as long as desired. The pans maybe removed from the rack and replaced thereon independently. Draining means are provided for each group of pans to receive the excess syrup and guide it to a suitable receptacle. Each pan is made of large capacity as compared to those heretofore used and is preferably provided in its bottom with an opening arranged to occupy a position above the draining means for its group. A closure is provided for each opening so that the syrup may be held in the pan until time for draining when the closure is removed, and the syrup flows into the draining means. When most of the syrup has been drained, the pans are tipped and held in that position to insure a thorough draining.

The invention is defined in the accompanying claims, and a clear understanding thereof will be obtained from the claims and the following specific description of the preferred form used as a basis. It is well understood, however, that the invention may be carried out with other specific structure than that now to be described.

Referring to the drawings Figure 1 is an end elevation of the rack and pans assembled in normal position. Fig. 2 is a rear elevation of the same with parts removed to shorten the length to the requirement of the sheet. Fig. 3 is a viewsimilar to Fig. 1 showing the elevating and lock ing means in position to hold the pans in tipped or draining position and the draining means in position to receive the excess syrup. Fig. 4 is a front view of the apparatus as arranged in Fig. 3. Figs. 5, 6, and 7 are detail views showing the elevating and locking mechanism for tipping and holding the pans in draining position. Fig. 8 is a detail sectional view of the forward end of the pan showing its draining opening and the removable closure therefor.

Referring to Fig. 4, the rack proper comprises a rectangular metal frame made up thereto. Extending from the members 5 at each end of the rack are the'horizontally arranged parallel tubes or rods 15. The

latter are securely bolted at their ends to said members. Connecting the members 6 (see Figs. 5 and 6) are similar tubes 16. These, however, are arranged to each have a limited vertical movement in slots 17 with which they connect by means of stud caps 18. A link 11 is pivoted at one end .to the stud 18 after the latter passes through its slot 17 The other end of link 11 is pivoted to the upper end of a link 13 which in turn is pivoted at its lower end on pivotstud 14, bolted to member 6. The handle 12 has oneend securely fixed in the end of link 11, as shown. The connections of the tubes 16 with the members 6 are in each case the same. That is to say, opposite parallel slots 17, one in each member 6, receive the studs 18 one at each end of a tube 16, .and these studs are each connected to a link structure 11 and 13, as described. When the tubes 16 are in their lower positions, the" in Fig. 5 to that shown in Fig. 7, the links 11 and 13 at each end of tube16 will be,

forced to the position shown. in Fig. 7. This movement of. the links 11 and 13 causes tube 16 to rise in the slots 17 at each end- The center 20 will lie, as shown in Fig. 7, to the left of the line joining centers'14 and. 18. The weight of the tube 16 tends to force links 11 and 13 further to the left,

but, inasmuch as the handle 12 is now resting against the pivot-stud 14, further movement is prevented. By this structure then,

a separate toggle-elevating means is pro means for raising, lowering, and locking the supporting tubes 16. Each tube 16, when in low down position, is parallel to and opposite a corresponding fixed tube 15. When a tube 16 is raised, it is still parallel with its corresponding tube 15 but slightly elc' vated above that tube. The crystallizing pans 1 are adapted to be supported at the front end on tubes 1.5 and at the rear end on tubes 16 in either raised or lowered position. e w

The type of pan designed for use in connection with this apparatus is best shown in Figs. 1 and 8. It comprises a rectangular pan 1 open at the top only but provided with a draining opening 2, centrally located near the front edge of the pan. A stopper 3, conveniently made of rubber and provided with string connection to a fingerring 4, is used to close and open this outlet 2 2. The pan is preferably of such a size that, when filled with candy to be crystallized, it is about the limit in weight. for the ordinary workman to lift and handle conveniently. In this way, the workman is kept to his greatest elficiency.

The drawings illustrate-a rack for holding four rows of pans, one above the other. The pans in each row are supported by longitudinal tubes 15 and 16 with the draining openings 2 in line one with the other. A draining gutter 20 is provided at the side of the rack for each row of pans, and each gutter is removably supported in swin ing brackets pivoted as shown (see Fig. 1 to the members 5. The brackets 21, supporting eachgutter 20, are arranged at different levels so that the gutter resting therein slants toward one end of the machine. These draining gutters and brackets are removable and are designed. for use only during the draining operation.

YVith the apparatus built as described, the preferred operation is as follows: Therack, as shown in Fig. 1, is rolled on thecasters 7 to the bench containing the candy to be crystallized. The operator takes one pan after the other from the rack, fills it nearly full, and replaces it. The stoppers 3'are in place, as shown in Fig. 8. When the pans are loaded, the-rack is rolled to the crystallizing fioor. The operator now fills each pan with the crystallizing syrup until the candy therein is completely immersed. This is conveniently done by a hose connection to the syrup tank and a motor operated pump under the controlv of the operator.

After the pans are filled, the rack remains, as shown in Fig. 1 usually during the night. In the morning, the operator places the draining gutters 20 in place-on the brack: ets 21 on the side of the rack and all slanting in the same direction. The stoppers 3 are then pulled by means of the finger-' rings 4, and the-excess syrup flows into the gutters 20 to any suitable receptacle placed at the end of the machine. When the greater part has left the pans 1, the operator, by means of handles 12 (see Figs. 3 and 4), elevates and locks the rear ends of each row of pans in tipped position. If desired the front ends of the pans may be lowered and thus tipped by mechanism equivalent to the elevating means and in this arrangement the rear ends would be held stationary. The full weight of pans, candy and syrup would then never need to be raised all together. The pans are left intipped position for some time. A large amount of syrup, which would otherwise stay in the pans, is thus caused to flow downwardly and out the openings 2 into the gutters. In this way, the pans and the candy therein are all thoroughly drained. When the draining operation is finished, the rack may be rolled to a bench on which the candy is emptied from the pans. It is desirable to then move the rack alongside a suitable receptacle and scrape any crystallized syrup adhering to the surface of the pans into said receptacle. The apparatus designed as described reduces the amount of scrapings from the pans to a minimum, first, because of the large volume of the pans in relation to their surface as compared to those formerly used, and, second, because of the thorough draining from each pan while in its tipped position. Where large quantities of candy are to be crystallized, the saving due to the small amount of scraping resulting from the process, is of material assistance in cutting down the cost of the goods.

From the foregoing description of the apparatus and operation, I believe the advantages of my invention will be clear to those skilled in the art. The structure is purposely reduced to the simplest form of which I am now aware for carrying out the crystallizing process. The full value of the apparatus, however, is best understood, not from a consideration of the bare structure alone, but, from a consideration of the structure in its relation to the use for which it is designed.

Having disclosed the best form and mode of using my invention, of which I am now aware, I wish it understood that the invention, as defined in the accompanying claims, may be carried out with various other specific structures which are not specifically disclosed herein.
